[0022] Embodiment

[0023] A device for purifying landscape water described in this embodiment, as Figure 1 and Figure 2 shown, includes a purification box 1. The top of the purification box 1 is a box cover, and a handle 18 is fixed on the box cover. When the box cover is specifically installed, one side of the box cover can be hinged to the purification box 1 through a hinge or a pivot. For example, the left side wall of the box cover can be hinged to the left side wall of the purification box 1, and then a lock for locking the box cover to the purification box 1 is provided on the other side opposite to the hinged side. The lock includes a movable part and a fixed part. The movable part is installed on the box cover, and the fixed part is installed on the purification box 1. Then, by combining the movable part and the fixed part of the lock, it is convenient to lock the box cover to the purification box 1. When in use, open the lock, and operating the handle 18 makes it convenient to open the box cover;

[0024] As Figure 1As shown in the figure, a first water pump 5 is provided on the left side of the purification tank 1. The water inlet end of the first water pump 5 is connected to a first water inlet pipe 6 that communicates with it. The water outlet end of the first water pump 5 is connected to a first water outlet pipe 3 that communicates with it. A first through hole that communicates inside and outside is opened at the top of the purification tank 1. The water outlet end of the first water outlet pipe 3 passes through the first through hole and is located inside the purification tank 1; this section of the solution as a whole constitutes a drainage component for draining the landscape water into the purification tank 1; the first water pump 5 is a known product, which is mainly a mechanical device for transporting and lifting water bodies; during use, the water inlet end of the first water inlet pipe 6 is placed in the landscape water, and then the first water pump 5 is turned on, and the landscape water can be injected into the first water inlet pipe 6 and then discharged through the first water outlet pipe 3. Because the first water outlet pipe 3 is located at the inner top position of the purification tank 1, the landscape water can be injected into the purification tank 1 from the inner top position of the purification tank 1;

[0025] In the specific implementation process, the first water pump 5 in the drainage component can be replaced by a turbine pump. The turbine pump is a known product, and it increases the pressure and flow rate of the fluid through its high-speed rotating turbine blades, thereby realizing the transportation of water;

[0026] As Figure 1 As shown in the figure, a second water pump 8 is provided on the right side of the purification tank 1. The water inlet end of the second water pump 8 is connected to a second water inlet pipe 9 that communicates with it. The water outlet end of the second water pump 8 is connected to a second water outlet pipe 7 that communicates with it. A second through hole that communicates inside and outside is opened on the right side wall of the purification tank 1. The water inlet end of the second water inlet pipe 9 passes through the second through hole and is located inside the purification tank 1; this section of the solution as a whole constitutes a discharge component for discharging the landscape water from the purification tank 1; the second water pump 8 is a known product, which is mainly a mechanical device for transporting and lifting water bodies; the water inlet end of the second water inlet pipe 9 is preferably located near the inner bottom of the purification tank 1. During use, the water outlet end of the second water outlet pipe 7 is placed in the landscape pool, and then the second water pump 8 is turned on, and the treated landscape water in the purification tank 1 can be injected into the second water inlet pipe 9 and then discharged into the landscape pool through the second water outlet pipe 7. By draining the landscape water into the purification tank 1 through the drainage component and then discharging the landscape water into the landscape pool through the discharge component, the purpose of water circulation can be achieved;

[0027] In the specific implementation process, the second water pump 8 in the discharge component can be replaced by a turbine pump. The turbine pump is a known product, and it increases the pressure and flow rate of the fluid through its high-speed rotating turbine blades, thereby realizing the transportation of water;

[0028] As Figure 1As shown, a box body 4 for protecting the first water pump 5 and the second water pump 8 is sleeved outside both of them, and the box bodies 4 are both fixed on the purification tank 1; the top of the box body 4 is a box cover, and the installation method of the box cover is the same as that of the box cover on the top of the purification tank 1, so it will not be elaborated here; when the box body 4 is installed, the right side wall of the box body 4 outside the first water pump 5 is fixed on the left side wall of the purification tank 1, and the left side wall of the box body 4 outside the second water pump 8 is fixed on the right side wall of the purification tank 1; the first water pump 5 and the second water pump 8 are both installed on the inner bottom of the corresponding box body 4; through holes for the first water outlet pipe 3 and the first water inlet pipe 6 to pass through are provided on the box body 4 outside the first water pump 5, and through holes for the second water outlet pipe 7 and the second water inlet pipe 9 to pass through are provided on the box body 4 outside the second water pump 8, so as to facilitate the installation of the water inlet pipe and the water outlet pipe; therefore, through the design of the box body 4, the problem that the first water pump 5 and the second water pump 8 may collide and be damaged is avoided as much as possible, and the service life of the first water pump 5 and the second water pump 8 is increased as much as possible;

[0029] As Figure 1 and Figure 2 shown, a limiting frame 16 is arranged in the purification tank 1, and the limiting frame 16 communicates up and down and has no front side wall; from Figure 2 the orientation in the figure, the top view direction of the limiting frame 16 is in an inverted "U" - shaped structure. Preferably, the left side wall of the limiting frame 16 is attached to the left inner side wall of the purification tank 1, the right side wall of the limiting frame 16 is attached to the right inner side wall of the purification tank 1, and the front side of the limiting frame 16 is also attached to the front inner side wall of the purification tank 1. Through this attachment design, during the water purification process, impurities in the water are prevented from leaking out through the gap between the limiting frame 16 and the purification tank 1 as much as possible;

[0030] As Figure 1As shown, several filter meshes for purifying landscape water are horizontally arranged in the limit frame 16, and several filter meshes are arranged at equal intervals from top to bottom in sequence; the attributes of several filter meshes are all different. For example, in this design, the filter mesh can be composed of three pieces. The uppermost filter mesh is a common filter mesh 15, which can preliminarily filter impurities such as silt, leaves, and excrement in the landscape water; the middle filter mesh is a quartz sand mesh 14, and the quartz sand mesh 14 can effectively remove pollutants such as suspended substances, sediment, colloid, iron, organic matter, pesticides, manganese, bacteria, and viruses in the landscape water, significantly improving the water quality; the lowermost one is an activated carbon mesh 13. Due to its strong adsorption performance, the activated carbon mesh 13 plays an important role in water treatment. It can effectively remove various organic substances in the water and significantly reduce the content of these harmful substances in the water; in addition, the surface of the activated carbon mesh 13 has strong oxidation performance and can kill or inhibit microorganisms in the water, such as viruses, bacteria, and protozoa, etc.; thus effectively preventing water pollution and deterioration and ensuring the safety and hygiene of water quality; during use, the first water outlet pipe 3 is located above the common filter mesh 15. Therefore, the landscape water is purified successively through the common filter mesh 15, the quartz sand mesh 14, and the quartz sand mesh 14, and finally flows to the position at the bottom of the purification tank 1; because the limit frame 16 has no front side wall, after several filter meshes are installed in the limit frame 16 at equal intervals, the filter meshes can be cleaned from the front side direction of the limit frame 16;

[0031] As Figure 1 and Figure 3 shown, a first sliding groove for the front-back sliding of the filter mesh is opened on the limit frame 16, and the filter mesh is in front-back sliding fit with the first sliding groove; when the first sliding groove is opened, a first sliding groove is opened on the left inner wall, right inner wall, and rear inner wall of the limit frame 16 corresponding to each filter mesh. The left side wall of the filter mesh is in front-back sliding fit with the first sliding groove on the left inner wall of the limit frame 16, the right side wall of the filter mesh is in front-back sliding fit with the first sliding groove on the right inner wall of the limit frame 16, and the rear side wall of the filter mesh is in front-back sliding fit with the first sliding groove on the rear inner wall of the limit frame 16; therefore, the activated carbon mesh 13, quartz sand mesh 14, and common filter mesh 15 in the filter mesh can all be installed in the limit frame 16 by means of front-back sliding, and later, the activated carbon mesh 13, quartz sand mesh 14, and common filter mesh 15 can also be disassembled from the limit frame 16 by means of front-back sliding; when the filter mesh slides into the first sliding groove, preferably, the front side wall of the filter mesh fits with the front inner wall of the purification tank 1, from Figure 2The orientation in [description] can be seen, so as to prevent impurities in the landscape water from leaking out through the gap between the filter screen and the front side wall of the purification tank 1; later, for the convenience of simultaneously removing the filter screen on the limit frame 16, the limit frame 16 can be flipped so that the side without the side wall of the limit frame 16 contacts the ground, and then the limit frame 16 is moved upward. Since the limit frame 16 and the filter screen are in sliding fit, when the limit frame 16 is moved upward, the filter screen on the limit frame 16 will move downward simultaneously under the action of gravity, thus realizing the separation between the limit frame 16 and the filter screen;

[0032] Such as Figure 1 , Figure 2 And Figure 3As shown in the figure, a toothed plate 17 is provided on the purification box 1. The toothed plate 17 is detachably connected to the rear side wall of the limit frame 16. Second sliding grooves for the up and down sliding of the toothed plate 17 are provided on the left and right inner side walls of the purification box 1. The toothed plate 17 is in up and down sliding fit with the second sliding grooves. A groove is provided on the rear inner side wall of the purification box 1, and a gear 20 meshing with the toothed plate 17 is arranged in the groove. A through groove communicating with the inside of the groove is provided on the right side wall of the purification box 1, and a rotating shaft 12 is independently inserted into the through groove. The left end of the rotating shaft 12 penetrates into the groove and is rotatably connected in the groove, and its right end is connected with a servo motor 11 for driving its rotation. The gear 20 is sleeved on the rotating shaft 12. The servo motor 11 is installed on the right side wall of the purification box 1 through a mounting plate 10. This section of the solution as a whole constitutes a driving assembly for driving the limit frame 16 to move out of the purification box 1. When the toothed plate 17 specifically realizes up and down sliding, the left side wall of the toothed plate 17 is in up and down sliding fit with the second sliding groove on the left inner side wall of the purification box 1, and the right side wall of the toothed plate 17 is in up and down sliding fit with the second sliding groove on the right inner side wall of the purification box 1. When the toothed plate 17 is located in the second sliding groove, its rear side wall fits against the rear inner side wall of the purification box 1, thus preventing impurities in the landscape water from leaking out between the rear side wall of the toothed plate 17 and the purification box 1. Therefore, through the design of the second sliding groove, it is not only convenient for the toothed plate 17 to slide up and down, but also can limit the toothed plate 17. To achieve meshing, the rear side wall of the toothed plate 17 is the side wall with tooth grooves, so it can mesh with the gear 20 in the rear groove. When the left end of the rotating shaft 12 realizes rotational connection, the left end of the rotating shaft 12 can be installed in the groove through a bearing. A blind hole is provided on the left side wall of the groove, the outer ring of the bearing is fixed in the blind hole, and the left end of the rotating shaft 12 is fixed to the inner ring of the bearing. Therefore, the rotating shaft 12 realizes rotational connection and can rotate freely. When the servo motor 11 is specifically installed, the left side wall of the mounting plate 10 is fixed to the right side wall of the purification box 1, the servo motor 11 is installed on the top of the mounting plate 10, the right end of the rear rotating shaft 12 is connected to the servo motor 11, the servo motor 11 is electrically connected to a control switch and a battery. The battery is used to supply power to the servo motor 11, and the control switch is used to control the start and stop of the servo motor 11. Both the control switch and the battery can be installed on the top of the mounting plate 10. During use, when the servo motor 11 is turned on, the servo motor 11 can drive the rotating shaft 12 to rotate. During the rotation of the rotating shaft 12, because the gear 20 is sleeved on the rotating shaft 12, the gear 20 can be driven to rotate. Because the gear 20 meshes with the toothed plate 17, when the gear 20 rotates, the toothed plate 17 can move up and down. According to Figure 3When the gear 20 rotates clockwise, the tooth plate 17 can be driven to move upward, and when the gear 20 rotates counterclockwise, the tooth plate 17 can be driven to move downward; because the limit frame 16 is detachably fixed to the tooth plate 17, the limit frame 16 can be driven to move up and down, and at the same time, the activated carbon mesh 13, quartz sand mesh 14 and ordinary filter mesh 15 on the limit frame 16 also move up and down with the limit frame 16; when in use, if it is necessary to take out several filter meshes from the purification box 1 for cleaning, the box cover of the purification box 1 is opened, and then the servo motor 11 is rotated to drive the gear 20 to rotate to make the tooth plate 17 move upward, which can drive the limit frame 16 and several filter meshes to move out from the top position of the purification box 1 together, because the limit frame 16 can be The disassembly is connected to the tooth plate 17, so by removing the limit frame 16 from the tooth plate 17, it is convenient to disassemble the multiple filter screens on the limit frame 16, thereby facilitating the cleaning of the multiple filter screens. During the cleaning process, if the filter screen needs to be cleaned more thoroughly, the filter screen can be pulled out of the limit frame 16 for cleaning. After cleaning, the limit frame 16 is connected to the tooth plate 17, and then the servo motor 11 rotates to drive the gear 20 to rotate to move the tooth plate 17 downward, which can drive the limit frame 16 and the multiple filter screens to move back into the purification box 1 together, thereby achieving the purpose of installing multiple filter screens; therefore, in this use process, it is convenient to install and disassemble multiple filter screens at the same time;

[0033] In a specific implementation process, the driving assembly can have multiple grooves, the multiple grooves are on the same straight line, and the grooves are all connected to the through grooves. A gear 20 is provided in each rear groove, and the rotating shaft 12 passes through the through grooves and the grooves. The multiple gears 20 are all mounted on the same rotating shaft 12. Therefore, when in use, the multiple gears 20 are all engaged with the tooth plate 17. Therefore, through the design of multiple gears 20, the tooth plate 17 can be lifted more stably.

[0034] like Figure 1 and Figure 2 As shown, a "T"-shaped block 19 is fixed to the rear side of the limit frame 16, and a slot for engaging with the block 19 is provided on the tooth plate 17; when the engaging connection is implemented, the slot is provided on the front side wall of the tooth plate 17 and communicates with the top of the tooth plate 17, as shown in FIG. Figure 2In terms of the orientation, the clamping block 19 is in a "T" shape structure, and the inner part of the clamping groove is also in a "T" shape structure. The size of the clamping block 19 is slightly smaller than that of the clamping groove. Therefore, the clamping block 19 can be limited within the clamping groove. During use, since the clamping groove communicates with the top of the tooth plate 17, the clamping block 19 moves downward from the top position of the tooth plate 17 and is placed into the clamping groove, so as to achieve the purpose of limiting the clamping block 19. Thus, the limiting frame 16 is limited on the tooth plate 17. Since the limiting frame 16 and the tooth plate 17 are detachably connected, when it is necessary to disassemble the limiting frame 16 from the tooth plate 17, the clamping block 19 is moved upward, and the clamping block 19 can be removed from the clamping groove, so that the limiting frame 16 and the tooth plate 17 are separated. At this time, several filter meshes on the limiting frame 16 can be disassembled from the tooth plate 17. After the limiting frame 16 is installed on the tooth plate 17 through the clamping block 19, the rear side wall of the limiting frame 16 is attached to the front side wall of the tooth plate 17, thus preventing impurities in the landscape water from leaking out through the gap between the limiting frame 16 and the tooth plate 17.

[0035] As Figure 1 shown, two limiting blocks 2 for supporting the limiting frame 16 are fixed inside the purification tank 1. The limiting blocks 2 are arranged horizontally. The left limiting block 2 is fixed on the left inner side wall of the purification tank 1, and the right limiting block 2 is fixed on the right inner side wall of the purification tank 1. After the clamping block 19 on the limiting frame 16 is clamped and connected in the clamping groove, the bottom of the limiting frame 16 is placed on the top of the limiting block 2. Therefore, the limiting block 2 can support the limiting frame 16, avoiding the weight brought by the limiting frame 16 and several filter meshes from being applied to the clamping block 19, so that the clamping block 19 can be used more stably.

[0036] In the specific usage process: First, place the first water inlet pipe 6 in the landscape pool, and then turn on the first water pump 5 to pump out the landscape water, which flows through the first water outlet pipe 3 and into the upper part of the filter screen in the purification tank 1. Then, the activated carbon screen 13, quartz sand screen 14, and ordinary filter screen 15 in the multiple filter screens are used to filter and purify the landscape water respectively. Then, the purified water flows into the bottom of the purification tank 1. After that, place the second water outlet pipe 7 in the landscape pool and turn on the second water pump 8. Through the second water inlet pipe 9 and the second water outlet pipe 7, the purified landscape water can be re-discharged into the landscape pool. When multiple filter screens need to be cleaned regularly, first open the lid of the purification tank 1, and then turn on the servo motor 11. The servo motor 11 drives the rotating shaft 12 and the gear 20 to rotate. During the rotation of the gear 20, it meshes with the tooth plate 17, which can drive the tooth plate 17 to move upward. During the upward movement of the tooth plate 17, it can drive the limit frame 16 and multiple filter screens on the limit frame 16 to move out of the purification tank 1 at the same time. Then, take out the limit frame 16 from the tooth plate 17, which is convenient for cleaning multiple filter screens. After the cleaning is completed, reinstall the limit frame 16 on the tooth plate 17, and then the servo motor 11 drives the rotating shaft 12 and the gear 20 to rotate, making the tooth plate 17 move downward, thereby driving the limit frame 16 and several filter screens to move downward, so that multiple filter screens can move into the purification tank 1 at the same time to achieve the purpose of installation. Therefore, in this usage process, multiple filter screens on the limit frame 16 can be moved out of the purification tank 1 at the same time to achieve the purpose of convenient disassembly and cleaning, and multiple filter screens on the limit frame 16 can also be installed in the purification tank 1 at the same time to achieve the purpose of installation, thus facilitating the disassembly and installation of multiple filter screens at the same time, and solving the problem in the prior art that it is not convenient to disassemble and install multiple filter screens.
